Interpretation of Soil Map for Available Moisture in a Given Climatic Type

Soil maps which are the end products of soil survey, are utilized to abstract soil characteristics through soil classification and define environmental relationships of soils to evolve guidelines for proper use and management. The concept that the soils differ in their characteristics within an area of a given climatic type is reflected in moisture properties pertaining to the soils of the area. Geographical distribution of soil series and associations in the semi-arid tract of Hissar, Haryana having varying available moisture capacities is indicated in the map. The available moisture capacity as related to rainfall pattern and potential evaporation is discussed. Utilization of moisture by specific crops in different soils is also highlighted and accordingly demarcation of bench mark soil areas along with their suitability for specific crops is attempted to furnish reliable data for research and extension workers.
